Catering waste management
- 1. Compliance Seminar Catering Waste Management 10 September 2014
- 2. Agenda • Introduction • The ‘Hot-Spots’ • The Problems • The Law • CBio • The Solutions
- 3. Introduction • 100,000’s FOG related blockages in the UK, costing £80m p.a. to clear • Serious environmental consequences • Majority are caused by commercial catering establishments – 400,000 in the UK • Law requires them to deal with their FOG – few do
- 4. The Hot-Spots • Dishwashers • Potwash / Rinse Sinks • Combi-ovens • Macerators • Floor channels • Potato rumblers • Decarboniser units
- 5. The Problems
- 6. The Law • Building Regulations – PtH1 para 2.21 • Water Industry Act 1991 • Environmental Protection Act 1990 – Duty of Care • Environmental Protection Act 1990 - Statutory Nuisance • Animal By-Products Regulations EC - 1774/2002 (ABPR) • Building Act 1984 • Food Safety Act 1990 • Bathing Water Regulations 2008
- 7. The Solution These all have a role to play • Training • Management • Interception • Active • Passive • Treatment • Biological • Chemical • Enforcement • By Management • By You
- 8. Training & Management There’s one simple message: “DON’T PUT IT DOWN THE DRAIN!” • Clarity • Consistency • Ownership • Assigned Responsibilities • Issues • Management Understanding • Staff Turnover • Staff Motivation • Time • Management Reinforcement
- 9. Interception • ACTIVE – point of source grease/food separation and collection • Examples – GB GRU, Fatstrippa, Grease Shield, Grease Guardian, Big Dipper, Food strainers PRO’s CON’s Can be highly effective – 95% efficiency Expensive Minimal staff maintenance – 1-2 min/day Difficult Installation (gravity discharge dish washers) Doesn’t hold grease long enough to cause smells Unsympathetic if you forget to service Unsympathetic if you forget to service Requires daily staff maintenance
- 10. Interception • PASSIVE – designed to separate grease and hold it until emptied • Includes small under-counter traps from 5lt to large under-ground traps of 5,000 lts PRO’s CON’s Cheap Unhygienic if not cleaned regularly Simple Rarely emptied as often as they should be Many suppliers / installers Smells / floods Work well if correctly sized Expensive contractor required to clean properly Rarely correctly sized – space restrictions. Needs minimum residence time.
- 11. Treatment • BIOLOGICAL – bacteria / enzymes used to digest FOG in the drainline • Can be used in small drains, pump stations, sewer lines and treatment works PRO’s CON’s Cheap Requires regular top-ups Simple installation Can struggle if incorrectly located / short residence time. Easily maintained On-going maintenance/fluid cost Works well if correctly located and in the right environment Enzymes – ‘single-use’ product ‘Fit & Forget’ Bacteria – Continued effect after dosing
- 12. Treatment • CHEMICAL – chemicals used to breakdown FOG in the drainline • Can be used in small drains, pump stations, sewer lines and treatment works PRO’s CON’s Cheap Frequently uses hazardous chemicals Simple application Can damage downstream assets Easily maintained FOG recombines after initial breakdown ‘Single-use’ product Reactive application

- 17. GreaseBeta GRU Features & Benefits • Automatically removes 95% of waste oil • Traps food particles • Easy to maintain • Reliable – no moving parts Service requirements • Daily by staff • 6M by CBIO engineer
- 18. McD’s Oakwood Leeds • Oakwood, Leeds GRU Trial (1 month) • Key Facts: – Removed 78 ltrs of FOG – Removed 208 ltrs of wet food solid waste

- 20. GreaseBeta GRU - Results The Site: • Medium sized food led pub • Producing c.1,400 covers/week The Unit: • GRU 2 installed on trial in January 2012 The Trial: • Waste food and oil collected for a 5 day period in March during which the site was relatively quiet. The Results: • Over 7kg of food waste and at least 5lt of waste oil was collected. • This represents over 1 ton of waste food and oil collected p.a. • FOG levels in the outlet measured at <4ppm The Conclusions: • An average kitchen produces at least: • 7g food waste/cover • 5ml oil waste/cover • GB GRU reduced the BOD load on the STP by c.50%
- 21. GreaseBeta Strainer • GB Strainer is a stand alone food solids strainer. • Easily installed beneath the potwash and rinse sinks. • Simple slide out catch basket, capable of collecting in excess of 1,000kg of food waste p.a. • Can be used in conjunction with GB BIO & up-stream of GB GRU. • Cannot be by-passed by the operator and does not restrict sink discharge flow rates. The GB Strainer removes all food waste, a key component of FOG related issues
- 23. GreaseBeta Trap • The GB Trap is a full range of internal fat traps 5lt – 200lt volume • Each trap comes with an in-built solid strainer • Works in conjunction with GB BIO units to minimise grease build-up inside the unit • The GB Clean service ensures that any trap can be emptied as often as is required • CBIO can specify and supply large (c. 5,000 lt) out-door GRP underground, 2 or 3 stage grease separators. CBIO can also arrange for the civil engineering work to be undertaken if required
- 24. GreaseBeta BIO Advantages • Compact pump easy to install and maintain battery operated • Utilises entirely natural biological fluid and processes • Complete digestion (no disposal costs) • Fully maintained service available • Unlimited pump guarantee providing CBIO fluid in use (third party damage not covered) NB - When used with an existing grease trap will significantly reduce the required desludge frequency.
- 25. GreaseBeta Aer8 • GB Aer8 is a biological Pump Station Conditioner. • The system doses a range of bacteria, macro and micro nutrients into the sump and also injects 240 lt/min of air into the effluent. – This converts the septic sump into an aerated bioreactor. • The unit requires a mains power source and access to the pump station itself, all usually available via the control kiosk. The GB Aer8 eliminates pump station odours, fat blockages and septicity
- 26. GreaseBeta Clean • Grease management equipment will only perform consistently if it is looked after. – All GB units can be installed, serviced and maintained by the in-house service engineers. – This includes fat trap emptying as part of a regular service regime. – All waste collected is fully traceable to an official waste collection site. – All maintenance and service visits are pro-actively managed by our experienced administration team.
